<p class="rvps2"><span class="rvts6"><br/></span></p>
<p class="rvps2"><span class="rvts6">As the name describes, this tool parses the iNES header of NES ROM file, which is called </span><a class="rvts70" href="https://wiki.nesdev.com/w/index.php/INES" target="_blank">iNES header</a><span class="rvts6">, to a human understandable information. You can change various settings of the ROM, such as Mapper#, CHR RAM Size, PRG RAM Size, mirroring type, region... etc.</span></p>
<p class="rvps2"><span class="rvts6"><br/></span></p>
<p class="rvps2"><span class="rvts97">This tool is experimental, and incorrect modification to the header may cause the ROM fail to run or some unpredictable </span><span class="rvts98">consequences. Use at your own risk.</span></p>
<p class="rvps2"><span class="rvts98"><br/></span></p>
<p class="rvps2"><span class="rvts21">About iNES Format</span></p>
<p class="rvps2"><span class="rvts6"><br/></span></p>
<p class="rvps2"><span class="rvts6">The first 16 bytes of each iNES format file store some important settings of the dumped ROM in binary. When NES Emulator loads the game, it will determine how to simulate based on these settings.</span></p>
<p class="rvps2"><span class="rvts6">The iNES format currently has 2 versions, </span><a class="rvts70" href="https://wiki.nesdev.com/w/index.php/INES" target="_blank">1.0</a><span class="rvts6"> and </span><a class="rvts70" href="https://wiki.nesdev.com/w/index.php/NES_2.0" target="_blank">2.0</a><span class="rvts6">.&nbsp;</span></p>
<p class="rvps2"><span class="rvts21"><br/></span></p>
<p class="rvps2"><span class="rvts21">Modify The iNES Header</span></p>
<p class="rvps2"><span class="rvts6"><br/></span></p>
<p class="rvps2"><span class="rvts6">For historical reason, some ROM file has misinformed or malformed information in their header, they can't run normally or even fail to run in FCEUX or other emulators. This tool can help for diagnose and fix the problems. Sometimes ROM hacking also requires modifying the header.</span></p>
<p class="rvps2"><span class="rvts6">To edit the header of a ROM file, just click the menu and select the file. If a ROM is already loaded, it will edit the current ROM. After modification, press "Save as..." button to save to a new file.</span></p>
<p class="rvps2"><span class="rvts6">For safety purposes, we recommend you always save the header modified ROM to a new file, or backup the original ROM before editing.</span></p>
<p class="rvps2"><span class="rvts6">If you regretted before saving, you can press "Restore" button, all the settings will back to the original.</span><span class="rvts6"></span></p>
